[PATCH 4/4] tools/perf/tests: Update probe_vfs_getname.sh script to use perf build --has

[Aditya Gupta]

From: Athira Rajeev <atrajeev@xxxxxxxxxxxxxxxxxx>

In probe_vfs_getname.sh, current we use "perf record --dry-run"
to check for libtraceevent and skip the test if perf is not
build with libtraceevent. Change the check to use "perf build --has"
option
